Program.Main: AutomationTool exiting with ExitCode=1 (Error_Unknown)

I want to package my game for Android, but when packaging, it gives me this error: “Program.Main: AutomationTool exiting with ExitCode=1 (Error_Unknown)”

I have tried couple suggested things to do such as Veryfying my 4.13 version from Epic launcher, did not help.
I also have made sure that all my settings for packaging are correct. They have worked in the past when I first set them up and was able to package without problem. Now that I put a long pause to my game and returned, finished it and wanted to package, it gives me trouble.

Only changes I have done to my project are added assets and some blueprint code, nothing out of the ordinary. Could this perhaps have any affect on packaging, no?
